To all whom t may concern:

Be it known that I, GEORGE S. Gnssnrm, a citizen of the United States,residing at Selinsgrove, in the county of Snyder and State ofPennsylvania, have invented certain new and useful mprovementsinDirigible VHeadlights; and do hereby declare the following to be a full,clear, andexact description of the invention, such as will enable othersskilled in'the art to which it appertains to make and use the same.

My invention relates to new and useful. improvements in light .shiftingmeans for automobiles and similarly propelled vehicles, and my object isto provide means in connection with the steering rod of the vehicle for.moving the lamps, whereby the light, will he reflected in the directionin which the vehicle is to move.

A further object is to provide brackets for attaching the lamps to the'steering inechanisin.

taking up wear between parts of the steerin mechanism land preventrattling thereoi. And a further object is to provide means forattachingthe steering mechanism ,to parts oi' a vehicle.

Other objects and advantages will be hereinafter set forth and moreparticularly pointed out in the accompanying specilication.

In the accompanying drawings which are made a part otthis application,Figure 1 is a front 'elevation of the steering mechanism showing thelamps attached thereto. Fig. 2 is a sectional view thereof seen on line2-2 oi'ig. 1. Fig. f3 is a vertical central sectional View through Ithelamp supporting means with the steering mechanism disengaged therefrom,and Fig. i is sectional view thereof as seen on line 1 4 of lFig. 3.'

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1. indicates thesteering rod, such as is com monly used .for steering the front wheelsof an automobile, or similarly propelled vehicles, and 2 indicates anauxiliary steering rod which is connected to the steering rod 1 throughthe medium of a pitman 3, said pitinan having at opposite ends sockets iand 5 which engage balls not shown) attached to stems 6 and '7respectively carried by blocks 8 and 9 which are clamped into engagementA further object is to provide means for 'with the rods 1 and 2respectively, and it will be readily seen that when the steering rod lis given an end-wise thrust to change the course of the wheels of thevehicle, the auxiliary steeringrod 2 will be moved longitudinally, inthe saine direction.

Mounted upon any suitable part of the'.

vehicle, preferably the axle, arebrackets 10, said brackets havingcircuiar-langes 11 to form seats .tor the lower ends of the tubularcasings 12., said lianges having split portions, upon opposite sides ofwhich are' formed. integral ears 13 which are drawn together' by meansof bolts 14e, 'thereby securely locking the casings into engagement withthe bracket.

Extending vertically through the casings 12 Aare standards 15 which arethreaded for a portion of their length, the upper and lower ends of thestandards having hat pered faces 16 for purposes to be hereinafter set,forth, said shafts having threaded thereon', collars 17, which fitwithin the oppositeendsof the casings 12, and movably mounted on saidstandards between .the collars 17 are collars 18, the upper collars 18having sleeves 18 extending 'downwardly therefrom and fitting over the`unthreaded portions of said standards, th/f said sleeves havingshoulders which abut e against the shoulders of the unthreaded portionsof the standards, said collars having races 19 formed in their meet ingacesin which are placed bearing balls 20, 'the 'collars 21,8 being heldin juxtaposition to the threaded collars 17 by means of coil springs 21which. extend from the upper to the lower collars 18 and around thesleeves of the upper collars. After the collars 17 have been properlypositioned upon the standards 15 they are lined thereto by means ofsplines 22, orin any suitable mannerrlhe upper ends oi the casings 12are provided with caps 23 which are likewise provided with splitportions'having ears 2li on opposite .sides thereof which are clampedtogether by means of bolts 25 for locking the cap into engagement withthe casings,

said brackets and caps having openings 26 and 27 respectively throughwhich project the portions of the standards 15 having 'Hat faces 16.

between the standards 15 and another.

' structed and applied to practically steering rod, while the oppositeends thereof are provided with oblong tapered slots 29 which engage thelower tapered ends of the standards 'l5 and lit the flattened portionsthereof, said straps being held in engagement with the standards bymeans of nuts 30, the taper of the faces 1,6 being such as to hold thestraps out of engagement with the brackets, and it will be readily seenthat when the auxiliary steering rod is moved lengthwise the standardswill bc rotated a predetermined distance.

Fitting over the upper ends of the standards 15 and having openingstherethrough to it the flattened tapered faces of the standards l5, arebrackets 3l which are held in engagement with the standards by means ofnuts 32, the upper ends ot' said brackets supporting the lamps 33, whilethe brackets are so constructed that they can be positioned adjacent themud guard of the machine and still rotate without interfering therewith,the downward movement o' said brackets on the standards being likewiselimited by the. taper of said faces.` rlhe brackets l0 are provided withdepending stems 84 which extend through parts of the vehicle and areattached thereto by introducing bolts 36 ,into threaded openings in saidstems, the outer ends of the bolts having heads thereon which hold thestems in engagement vwithv the parts to which vthey are attached.d

ln operation, moved lengthwise to shift 'the direction of the travel ofthe wheels of vthe vehicle, the

' standards l5 will be rotated in such manner as to move the lamps so,as to reflect the rays of light therefrom directly in the path inlwhich the vehicle istraveling, thereby enabling the driver to observeany obstructions that might otherwise be encountered.

This device can be very cheaply conany make of car at a minimum expenseand without changing any of the parts of the car, other than providingan opening for the reception of the stems of the brackets which carrythe standards. l t will likewise be seen that as all of the parts of thedevice are constructed or" metal, it will be practically indestructibleand may be transferred from one machine to And it will likewise be seenthat .by providing the bearing balls the spring for holding the bearingcollars in engagement with the balls, any-wear between the parts will becompensated il r, and fan thermore that the collars at the outer endsol' the casings may be adi usted on the stand-I When the steering rod lis' ideama' brackets carried by parts of the vehicle, a

casing carried by each bracket, a carp the upper end of each casing, astandard et@ tending vertically through each casing and through the 'capand bracket at the ends thereof, said standard heini-g threaded adjacentits ends and having i t tapered Jfaces at its ends, a colla-r at eachend ot the casing,

lmeans to hold said collars in iixed relation with the standard, a pairof movable collars surrounding the standard between the lirst mentionedcollars and slidable on the standard, bearing' balls between the pairsof collars, means to yieldingly hold the movable collars injuxtaposition to the fixed' collars, means between'the lower ends ot thestand ards and the steering rod to cause said standards to rotate whenthe steering rod is shifted to guide the vehicle, and lamps tached .tothe upper ends oiisaid standards adapted to be rotated withthestandards.

2. ,ln a light shifting device, the combination with the steering rod ota vehicle; of a pair of brackets attached to parts of the vehicle, saidbrackets having flanges thereon, a. standard extending verticallythrough each bracket, said standard being exterior threaded at its endsand having dette tapered portions at each end, a casing sY in saidflange, collars threaded on to standard, one at each end' et the casing,
